Geoff Berry 8e556287ce [TargetRegisterInfo, AArch64] Add target hook for isConstantPhysReg(). ...

Summary:
The current implementation of isConstantPhysReg() checks for defs of
physical registers to determine if they are constant.  Some
architectures (e.g. AArch64 XZR/WZR) have registers that are constant
and may be used as destinations to indicate the generated value is
discarded, preventing isConstantPhysReg() from returning true.  This
change adds a TargetRegisterInfo hook that overrides the no defs check
for cases such as this.
